ION A filler metal is a metal added in the

making of joint during welding, brazing and soldering.(Ref: ASME Section IX, Definitions)

Filler wire is in wire and particle form.

URE Filler wires can be divided into two

designations:

a) Mandatory classification Designatorsb) Optional supplementary Designators

EXAMPLES FOR SELECTION OF FILLER WIRES

• Base metal = SA 335 • Welding process = GTAW• Filler wire = ?????

Referring ASME Section IX, Table QW-422, we will find where does this material (base metal) lies and find its:

• Grade• P number• Chemical composition

Material Grade = TP304LWelding process = GTAW Filler wire = ????

CONCLUSION

CONCLUSION

• Selection of filler wire depends on: Welding process Base metal SFA Joints

• Reference ASME Section IX ASME Section II part C
